Nightmare scrolls, town stash, backpack, runs, and the music system

1. Nightmare Scrolls

Consumable items that trigger standalone boss fights. Scrolls are rare drops that let you challenge a powerful nightmare boss outside of normal runs.

Drop Mechanics

• 1% chance per enemy kill
• Only drops at difficulty ≥ 5
• Scroll rarity follows the standard rarity roll

Scroll Properties

Each scroll stores multipliers determined at drop time using a gaussian distribution:

Property	Peak	Sigma	Floor	95% Range
HP multiplier	7.0	2.5	5.0	5.0 – 12.0
Damage multiplier	1.5	0.5	1.0	1.0 – 2.5

Using a Scroll

• Generates a nightmare boss at the scroll's stored difficulty
• Boss gets all 6 equipment slots filled
• Boss equipment rarity is floored to the scroll's rarity
• Boss HP = base_hp × hp_multiplier
• Boss damage = base_damage × damage_multiplier
• Fight runs entirely server-side (REST-based, like PvP)
• Full round-by-round replay shown in NightmareScene

Rewards

• Boss loot: added to backpack if you win
• Boss skin: same capture chance as regular boss kills

2. Town Stash (Storage)

Permanent item storage separate from your run backpack. Stash items are safe from salvage and don't count toward backpack capacity.

Storage Chests

• 1% drop chance per enemy kill (when difficulty ≥ player level)
• Stackable: up to 10 per stack
• Using a chest permanently unlocks 1 stash slot
• Max free slots: 12
• Max total slots: 30 (6×5 grid)

Stash Behavior

• Items in stash are protected from salvage
• Items in stash don't count toward backpack capacity
• Equipped items auto-unequip when moved to stash
• Toggle [ Stash: ON/OFF ] in BackpackScene replaces the stats panel with the stash grid

3. Backpack

Property	Value
Base capacity	24 slots
With ad boost	30 slots (+6)

• Items beyond effective capacity (expired boost) are frozen in the UI — shown dimmed with a lock icon, not interactive, not affected by salvage or sort
• Favorites sort to the top of the backpack, preserving relative order within each group

Mid-Run Travel Backpack

• Chest icon in RunScene opens a backpack overlay during a run
• Shows items collected in the current run only
• Drop mode: toggle [ Drop: ON/OFF ] to flag items for discard, freeing space for better loot
• On mobile: tap an item with Drop mode on, then tap the action bar to confirm
• Client-side only — no server interaction needed

4. Ad Boost

Rewarded video ad that gives temporary benefits:

Benefit	Value
Duration	60 minutes
Extra backpack slots	+6 (24 → 30)
XP bonus	+10%
Minimum level required	5

5. Runs & Retreat

• Max fights per run: 500
• You can retreat at any time to keep all collected loot and XP
• On death: same persistence — loot and XP from the current run are saved
• Retreat button has a 5-second cooldown

Auto-Retreat on Disconnect

If you lose connection, the server continues fighting headlessly on your behalf:

• Your character keeps fighting until death or the run ends naturally
• If your character dies while disconnected, loot is saved to a pending summary in the database
• On reconnect: RunScene shows “Resumed! X fights completed while away”
• If death occurred: the full run summary is shown in TownScene

6. Difficulty & Level Cap

Property	Value
Max player level	9,999
Max difficulty	9,999

Difficulty Cap per Player

Player Level	Max Difficulty
1	5
10	50
50	250
100	500
500	2,500
1,000	5,000
2,000+	9,999

37 unlockable music tracks that play continuously across all scenes in a playlist loop. Music progress is account-wide — shared across all characters.
